"Universal" LCD drivers

I have a couple old laptops kicking around that are obsolete, but their LCDs still work just fine and are decent enough resolution for me. I want to take one and use an old junk overhead projector I have and make a ghetto LCD projector. I've heard you can use those cheap chinese "universal" LVDS LCD driver boards (go on ebay and look), and that seems like a good deal, but has anyone had any experience with these? Do you have to program them or anything, or just plug/play?

most of the adapters will give you a standard video output (vga, displayport,hdmi.)
i know tinkernut did a video on this.
